Biography

Warren de Bruyn obtained his Ph.D. in Physical Chemistry from Boston College. He held post-doctoral and research faculty positions at the University of Miami and UCI before coming to Chapman. He is a physical/analytical chemist with research interests in atmospheric chemistry. Current research is focused on the oceanic cycling of sulfur species and oxygenated hydrocarbons into or out of the troposphere, which has implications for global climate change and the oxidative capacity of the troposphere.
